Used as a specialty intermediate in organic synthesis, particularly in the development of complex polycyclic compounds. Its strained ring system and aldehyde functional group make it valuable for constructing novel frameworks in pharmaceuticals and natural product analogs. It participates in cycloaddition and condensation reactions, enabling the formation of fused-ring systems important in medicinal chemistry and materials science. Due to its reactivity, it is also explored in catalysis studies and the design of functional organic molecules.
